Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C), suitable for bulk energy storage and smoothing on DC rails.
• Low Impedance for Power — Engineered for low impedance performance and recommended for switching power supplies; includes specified ripple current handling to support power conversion applications.
• Ripple Current Capability — Low-frequency ripple current 714 mA at 120 Hz and high-frequency ripple current 1.05 A at 200 kHz, enabling effective ripple absorption across common switching frequencies.
• Leakage and Dissipation — Specified leakage current of 510 µA and a tangent of loss angle (tan δ) of 0.14 (measured at 20 °C, 120 Hz), supporting predictable loss and self-heating behavior.
• Temperature & Endurance — Operating temperature range from -55 °C to +105 °C with a rated life of 5000 hours at 105 °C, providing long-term stability in elevated temperature environments.
• Package & Mounting — Radial-lead can package (φ16 × 15 mm) with 7.5 mm lead spacing and lead diameter compatible with through-hole assembly; available in bulk/bag packing for production lines.
• Environmental — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple current capability make this capacitor suitable for input/output filtering and energy buffering in SMPS designs.
• Power Rail Decoupling — Use on DC rails for bulk decoupling and transient absorption in embedded and industrial systems.
• General-Purpose Electronics — Applicable where a reliable, compact electrolytic capacitor is required for smoothing, timing, or hold-up functions across a wide temperature range.
